Scientists claim creation of blackest black yet

Scientists claim creation of blackest black yet Vantablack is the result of applying Surrey NanoSystems’ patented low-temperature carbon nanotube growth process to the UK Technology Strategy Board’s ‘Space for Growth’ programme, working alongside the National Physical Laboratory and Enersys’ ABSL Space Products division. The manufacture of `super-black` carbon nanotube-based materials has traditionally required high temperatures, preventing their direct application to sensitive electronics or materials with relatively low melting points. This, along with poor adhesion, prevented their application to critical space and air-borne instrumentation. The two year development and test programme was completed in December 2013, during which period Surrey NanoSystems successfully transferred its low-temperature manufacturing process from silicon to aluminium structures and pyroelectric sensors. As part of the programme, qualification to European Cooperation on Space Standardisation (ECSS) standards was also achieved. Vantablack has the highest thermal conductivity and lowest mass-volume of any material that can be used in high-emissivity applications. It has virtually undetectable levels of outgassing and particle fallout, thus eliminating a key source of contamination in sensitive imaging systems. It withstands launch shock, staging and long-term vibration, and is suitable for coating internal components, such as apertures, baffles, cold shields and Micro Electro Mechanical Systems (MEMS) –type optical sensors.

Kids can't use computers... and this is why it should worry you

‘So what do you teach?’ she asked as I worked on her presentation.
‘Computing’ I replied.
‘Oh… I guess these days you must find that the kids know more about computers than the teachers….’

If you teach IT or Computing, this is a phrase that you’ll have heard a million times, [...] Normally when someone spouts this rubbish I just nod and smile. This time I simply couldn’t let it pass.

‘Not really, most kids can’t use computers.’
